Using Ristretto technology, Castelli's Espresso Air Jacket provides us with unmatched warmth, comfort, and protection during the cold riding season. The fleece-lined fabric keeps us extra warm without sacrificing breathability, while the PFAS-free DWR treatment on the exterior sheds light rain and road spray to keep us dry. To further enhance warmth and protection, the double-layer cuff and the raw-cut lie-flat waist trap heat inside the jacket.
